DataStore waits too long before it's ready

Language and Async Model

Kotlin

The DataStore query doesn't do anything on the first load of the app, so I tried to listen for the DataStoreChannelEventName.READY event, but it took 1 minute from opening the app to when it got into Event Ready. Is there a way to sync data faster

When you start datastore sync starts in the background. You can use the observe query API to get the realtime sync results and you will be notified when sync is complete as well.

The solution is not working :(. When we use observe query API we got data only after DataStoreChannelEventName.READY event . We got an empty array (initial data) and full array after DataStoreChannelEventName.READY event . Problem is longing time on DataStoreChannelEventName.READY event on the first load of the app.

Is there any data saved locally when the app is started?

[nazarcybulskij]

@poojamat I don't save any data when the app is started. It is the first starting app

[taouichaimaa]

having the same issue, I resorted to loading static data from a json file. Any solutions?

A large dataset can cause DataStore sync to take more time to sync all the records and send the READY event. You can limit the number of records being synced using selective syncing.

my database consists of 20 tables. There is not much data at the moment, about 10 rows in each table. Sync takes more than 30 seconds ((I'm in apathy because I can't solve the problem ((

@nazarcybulskij Have you got any solution for faster sync ? I have only around 100 data but it takes more than 60 seconds.

[maheshordex]

@nazarcybulskij In ios with same user takes only 7 seconds it is big diff for sync between android and ios.

[mattcreaser]

#2703 dramatically improved sync times for datastore, bringing it much closer to the iOS time, and was released in Amplify 2.14.10. I'm closing this issue but please feel free to open a new one if necessary.
